The operationis as follows: The shock absorber being of the 'frictional type and ot relatively high capacity, will not come into action under any ordinary loads imposed upon the spring 12. 0n the contrary, the spring 12 will absorb all ordinary shocks in the usual manner. However. when an excessive shock occurs, the pressure transmitted through the spring 12 will be imposed on the follower block 22, thus causing the upper friction wedge blocks 18 to be iorced downwardly. Downward movement of the wedge blocks 18 will cause the latter to be separated diagonally as they slide over the corresponding faces ot the main wedge :20. Friction will thus be generated between the blocks 1S and wedge Q() and the relative movement resisted by the curved plates 21 which will tend to be straightened out against the side walls of the shell 17. As the blocks 1S are 'forced downwardly and separated, they in turn will torce the main wedge 2() downwardly, thus causing the lower Jfriction blocks 19 also to be separated and in turn compressing the spring plates 21. In this manner, high shock absorbing capacity is obtained because of the i`ri 1tionf ally engaging surfaces and excessive shocks thereby cushioned.

With the construction shown, it will be observed that l obtain a unilorin spreading action on all tour sides against the four sets of spring 'plates 21, each wedge block 1S or 19 moving diagonally and acting against two sets of spring plates 21. lVhen the excessive load is removed, it. is evident that the spring plates 21 will tend to return to their original condition, thus forcing the wedge. blocks 1S and 19 inwardly and in turn forcing the upper wedge blocks 18 upwardly. In order to prevent over-compression of the spring plates 21, the casing 23 may be limited in its downward movement by enigagement with the centering casing 24E as indicated at 37 in Figs. 2 and 3.

Although have herein shown and described what I now consider the preferred manner of carrying out the invention, the same is merely illustrative and l contemplate all changes and' modiications that come within the scope of the claims appended hereto.

I claim:

1. In a shock absorbing mechanism 'for vehicles having a body element. the combination with an axle, of a semi-elliptic main spring, and an auxiliary ,triction shock ab sorbing mechanism interposed between said main springend the axle at the center ot' the spring, the spring being directly supported on yone part of the mechanism and another part of the mechanism being directly supported on the aXlc.

2. in a shock absorbing mechanism ot the character described. adapted to be interposed between 4two members of a lvehicle or the like to cushion shocks. in combination: a shell, a plurality ci friction blocks, springs disposed between said blocks and the ivalis of the shell, and spreader means frictionally coacting with said blocks and adapted to separate the same to compress said springs upon pressure applied to the blocks, said blocks being bodily movable with respect to the shell and `adapted to have pressure applied thereto in lines parallel to said movement.

3. ln a shock absorbing mechanism ot the character described. the combination with a shell. ot a plurality of Jfriction blocks bodily movable with respect to the shell, spreader means trictionally cooperating with said blocks, and plate springs interposed between the blocks and the walls of the shell.

4. ln a shock absorbing mechanism, the combination with a shell, of 'a plurality of friction blocksa single wedge frictionally `coperable with all of said blocks, and

spi-in means interposed between said blocks and the side walls ot the shell, said blocks being bodily movable with respect to the shell and adapted to have pressure applied thereto in lines parallel to said movement.

ln a shock absorbing mechanism, the combination with a. shell, of two sets of bodily movable 'friction blocks disposed within the shell and longitudinally sepa' rated therein. a central block having wedgeacting faces copcrable with all of said friction blocks, and spring means interposed between the friction blocks and the side walls ot the shelh said two sets of blocks approaching each other upon actuation of the mechanism.

G. In a shock abso `-ins:r mechanism of the character descril'ieddhe combination with a shell. of two sets of friction blocks disposed within the shell and longitudinally separated therein, there being two Jfriction blocks in each set, a Yfour-faced wedge interposed between the inner and outer sets of friction blocks, one face of said wedge cooperating with each 'friction block, and spring means interposed between all of said friction blocks and the side walls of the shell, said two of blocks approaching each other upon actuation of the mechanism.

7. In a shock absorbing mechanism of the character described, the combination with a shell polygonal in cross section, of sets ot laminated springs disposed within said shell7
